High definition topography - data acquisition, modelling, interpretation
Convener: Jim Chandler  | Co-Conveners: Dirk Rieke-Zapp , Alexander Beer 
Advances in close-range surveying technology (photogrammetry/laser-scanning) allow geomorphologists and geoscientists to benefit from data at both higher spatial resolution and improved precision. This session provides an opportunity for scientists to share experiences and develop their expertise using these rapidly evolving and increasingly cost effective technologies. Activities are of interest to those involved in 3D reconstruction, change detection and process quantification for: geomorphology, earth science, hydrology, agriculture, forestry, glaciology, geology, surface roughness and climate change studies.
This session is organised by ISPRS Commission V Working Group V/5 "close range measurements for bio and geoscience" (formerly V6 - "Close range morphological measurements for the earth sciences"- 2008-12- While the ISPRS commission meetings are typically visited by professionals of geodesy, a similar session at EGU allows improved communication between professional surveyors and geomorphologists.
